A liquid reservoir assembly 100 for a refrigerating system according to some embodiments of the present disclosure will be described in the following with reference to FIGS. 1 to 6.

As illustrated in FIGS. 1 and 2, the liquid reservoir assembly 100 for the refrigerating system according to some embodiments of the present disclosure includes a liquid reservoir 1, a gas input pipe 2, a gas output pipe 3 and a capillary 4. The liquid reservoir 1 may have a substantially cylindrical shape, the liquid reservoir 1 defines a liquid storage chamber 11 therein, and the liquid storage chamber 11 may be used to store a refrigerant, such that a filling quantity deviation of the refrigerant can be reduced, and a phenomenon of an excessive refrigerant or an insufficient refrigerant can be prevented from occurring. The liquid reservoir 1 may have a gas inlet 12 and a gas outlet 13. For example, as illustrated in the drawings, the gas inlet 12 may be disposed at a top of the liquid reservoir 1, and the gas outlet 13 may be disposed at a bottom of the liquid reservoir 1. Thus, the refrigerant can enter the liquid storage chamber 11 in the liquid reservoir 1 through the gas inlet 12, and flow out of the gas outlet 13 after finishing a subsequent heat exchange with the capillary 4, thus completing a circulation.

The gas input pipe 2 may be connected to the gas inlet 12 of the liquid reservoir 1, and the gas output pipe 3 may be connected to the gas outlet 13 of the liquid reservoir 1. The refrigerant can pass through the gas input pipe 2, flow into the liquid reservoir 1 via the gas inlet 12, flow out of the gas outlet 13, pass through the gas output pipe 3, and subsequently enter a compressor 6.

The capillary 4 may be attached to the gas input pipe 2 and/or the gas output pipe 3, and wound around an outer wall of the liquid reservoir 1. Thus, refrigerant liquid in the capillary 4 can achieve the heat exchange with the incompletely evaporated refrigerant in the liquid reservoir 1, so as to completely liquefy the refrigerant in the capillary 4 and to reach a supercooling effect, such that a supercooling degree can be increased, a refrigerating capacity per unit volume can be promoted, a refrigerating speed can be enhanced, refrigerating efficiency can be further improved, and an energy consumption can be reduced. Furthermore, since the heat exchange between the capillary 4 and the liquid reservoir 1 improves purity of the refrigerant liquid in the capillary 4, a noise produced by an airflow disturbance can also be reduced. Meanwhile, the purity of a refrigerant gas in the liquid reservoir 1 can also be improved, and a liquid strike phenomenon can be prevented from occurring in the subsequent compressor 6.

It should be noted that, the capillary 4 may be attached to the gas input pipe 2 and/or the gas output pipe 3. That is to say, the capillary 4 may be attached to the gas input pipe 2, as illustrated in drawings. In this way, the refrigerant in the capillary 4 can perform the heat exchange with the refrigerant in the gas input pipe 2, thereby improving the purity of the refrigerant liquid in the capillary 4. Alternatively, the capillary 4 may be attached to the gas output pipe 3, such that the refrigerant in the capillary 4 can perform the heat exchange with the refrigerant outflowing from the liquid reservoir 1, thereby improving the supercooling degree of the refrigerant. Further alternatively, the capillary 4 may be attached to the gas input pipe 2 and the gas output pipe 3 at the same time, that is, one end of the capillary 4 is attached to the gas input pipe 2, a middle portion of the capillary 4 is wound around the outer wall of the liquid reservoir 1, and also, the other end of the capillary 4 is attached to the gas output pipe 3, such that the capillary 4 can achieve a sufficient heat exchange with the liquid reservoir 1, and thus the purity of the refrigerant liquid in the capillary 4 can be high, thereby further improving the refrigerating efficiency.

In the liquid reservoir assembly 100 for the refrigerating system according to some embodiments of the present disclosure, by attaching the capillary 4 to the gas input pipe 2 and/or the gas output pipe 3, and by winding the capillary 4 around the outer wall of the liquid reservoir 1, the refrigerant in the capillary 4 can achieve the heat exchange with the incompletely evaporated refrigerant in the liquid reservoir 1, so as to completely liquefy the refrigerant in the capillary 4 and to reach the supercooling effect, such that the supercooling degree can be increased, the refrigerating capacity per unit volume can be promoted, the refrigerating speed can be enhanced, the refrigerating efficiency can be further improved, and the energy consumption can be reduced. Moreover, the liquid reservoir 1 can reduce the filling quantity deviation of the refrigerant, and prevent the phenomenon of the excessive refrigerant or the insufficient refrigerant from occurring, such that the refrigerating speed can be further enhanced, and the refrigerating efficiency can be improved. Meanwhile, since the heat exchange between the capillary 4 and the liquid reservoir 1 improves the purity of the refrigerant liquid in the capillary 4, the purity of the refrigerant gas in the liquid reservoir 1 can also be improved, such that the noise produced by the airflow disturbance can be reduced, and a probability of the liquid strike phenomenon occurring in the compressor 6 can be decreased.

According to some embodiments of the present disclosure, as illustrated in the drawings, the capillary 4 may be attached to the gas input pipe 2, such that the refrigerant in the capillary 4 can achieve the heat exchange with the refrigerant in the gas input pipe 2, the purity of the refrigerant liquid in the capillary 4 can be further improved, and the refrigerating efficiency can be enhanced.

In some embodiments, as illustrated in the drawings, an inlet end 41 of the capillary 4 may be wound around the gas input pipe 2 and an outlet end 42 of the capillary 4 may be wound around the outer wall of the liquid reservoir 1. Thus, on the one hand, a stability of the capillary 4 being wound around the liquid reservoir 1 can be enhanced, so as to avoid falling off of the capillary 4; on the other hand, since the refrigerant from the inlet end 41 of the capillary 4 can achieve the heat exchange with the gas input pipe 2, a vast majority of the refrigerant has become liquid, only a small amount of the refrigerant is in a gaseous state and is mixed in the liquid, and such gaseous refrigerant is further liquefied while passing through the capillary 4 wound around the liquid reservoir 1, such that all the refrigerants finally entering the evaporator 8 are liquid, the refrigerating capacity per unit volume of the refrigerant is ensured to be maximized, the heat exchange efficiency is improved, the temperature reducing speed is increased, and the energy consumption is reduced. Meanwhile, since the purity of the refrigerant liquid in the capillary 4 is high, the noise caused by the air turbulence is effectively avoided.

As one embodiment, as illustrated in the drawings, the capillary 4 may be bound to the gas input pipe 2 by a tape 5, so as to improve the stability of the capillary 4 being attached to the gas input pipe 2, and to reduce the probability of the capillary 4 falling off

In some embodiments, the tape 5 may be a heat-transfer tape 5. In this way, the heat exchange between the capillary 4 and the gas input pipe 2 is facilitated. Further, the tape 5 may be an aluminum-foil tape 5. Since the aluminum-foil tape 5 is capable of conducting heat and has advantages of a good viscidity, a strong adhesive force, an anti-aging characteristic, etc., by binding the capillary 4 to the gas input pipe 2 with the aluminum-foil tape 5, the stability and the reliability of the capillary 4 being attached to the gas input pipe 2 can be further improved, and an influence on the heat exchange between the capillary 4 and the gas input pipe 2 can also be reduced.

According to some embodiments of the present disclosure, as illustrated in the drawings, the liquid reservoir 1 may be oriented in a vertical direction, the gas inlet 12 may be disposed at the top of the liquid reservoir 1, and the gas outlet 13 may be disposed at the bottom of the liquid reservoir 1. Thus, the refrigerant in the gas input pipe 2 may enter the liquid storage chamber 11 through the gas outlet 13, and perform a gas-liquid separation under the action of gravity. The refrigerant in the liquid storage chamber 11 performs the heat exchange with the refrigerant in the capillary 4, flows out of the gas outlet 13 of the liquid reservoir 1 after being further vaporized, and enters the subsequent compressor 6, thereby completing the circulation.

In order to improve the purity of the refrigerant outflowing from the liquid reservoir 1, the gas output pipe 3 may extend into the liquid reservoir 1. For example, in an example illustrated in the drawings, an end of the gas output pipe 3 may extend into the liquid reservoir 1 until above a central portion of the liquid reservoir 1, and the end may be inclined towards a side wall of the liquid reservoir 1. In this way, when the gas-liquid refrigerant mixture enters the liquid reservoir 1 through the gas inlet 12 at the top, the liquid refrigerant moves downwards under the action of gravity, and gathers at the bottom of the liquid storage chamber 11 to perform the heat exchange with the capillary 4 wound around the outer wall of the liquid reservoir 1, so as to be further vaporized. The gaseous refrigerant moves upwards, flows out of the gas output pipe 3, and further flows into the subsequent compressor 6. Also, the liquid refrigerant continues performing the heat exchange with the capillary 4. While performing the heat exchange with the refrigerant in the liquid reservoir 1, the refrigerant in the capillary 4 can be further liquefied, such that all the refrigerants entering the evaporator 8 can be liquid. Thus, the refrigerating capacity per unit volume of the refrigerant can be ensured to be maximized, the heat exchange efficiency can be improved, and the energy consumption can be reduced.

In some embodiments, as illustrated in the drawings, a part of the gas output pipe 3 extending into the liquid reservoir 1 may have multiple oil return holes 31. Since a lubricating oil in the compressor 6 will unavoidably enter a refrigerating system 200 when the compressor 6 compresses the refrigerant to work, by providing the multiple oil return holes 31 in the part of the gas output pipe 3 extending into the liquid reservoir 1, a separation of the refrigerant and the lubricating oil can be achieved, the refrigerant can flow into the subsequent heat exchange system, and the lubricating oil can return to a compression chamber of the compressor 6. On one hand, the influence of the lubricating oil on the refrigerating system 200 can be reduced; on the other hand, the lubricating oil can be recycled to avoid a phenomenon that the compressor 6 is burnt out due to operations with insufficient oil, so as to protect the compressor 6.

In some embodiments of the present disclosure, the gas input pipe 2 and the gas output pipe 3 are each a copper pipe. The copper pipe has a good heat-conduction performance and a low cost, such that, by employing the copper pipe, the heat exchange effects of the gas input pipe 2 and the gas output pipe 3 with the capillary 4 can be improved, and also, the cost can be reduced.

According to some embodiments of the present disclosure, the gas input pipe 2 and the gas output pipe 3 may be respectively connected to the liquid reservoir 1 by welding. In other words, the gas input pipe 2 may be welded at the gas inlet 12, and the gas output pipe 3 may be welded at the gas output pipe 13. Thus, during mounting, the gas input pipe 2 and the gas output pipe 3 may be welded to the liquid reservoir 1 firstly, and then welded to the evaporator 8 as a whole. These operations are convenient and simple, such that a mounting efficiency can be improved, and a production cost can be reduced.

In conclusion, in the liquid reservoir assembly 100 for the refrigerating system according to some embodiments of the present disclosure, by attaching the capillary 4 to the gas input pipe 2 and/or the gas output pipe 3, and by winging the capillary 4 around the outer wall of the liquid reservoir 1, the refrigerant in the capillary 4 can achieve the heat exchange with the incompletely evaporated refrigerant in the liquid reservoir 1, so as to completely liquefy the refrigerant in the capillary 4 and to reach the supercooling effect, such that the supercooling degree can be increased, the refrigerating capacity per unit volume can be promoted, the refrigerating speed can be enhanced, the refrigerating efficiency can be further improved, and the energy consumption can be reduced. Moreover, the liquid reservoir 1 can reduce the filling quantity deviation of the refrigerant, and prevent the phenomenon of the excessive refrigerant or the insufficient refrigerant from occurring, such that the refrigerating speed can be further increased, and the refrigerating efficiency can be further improved. Meanwhile, since the heat exchange between the capillary 4 and the liquid reservoir 1 improves the purity of the refrigerant liquid in the capillary 4, the noise produced by the airflow disturbance can also be reduced, the probability of the liquid strike phenomenon occurring in the compressor 6 can be reduced, and hence a service life of the compressor 6 can be prolonged.

The present disclosure further provides a refrigerating system 200, as illustrated in FIG. 7, the refrigerating system 200 according to some embodiments of the present disclosure includes a compressor 6, a condenser 7, an evaporator 8 and a liquid reservoir assembly.

Specifically, the condenser 7 may be connected to the compressor 6, and the liquid reservoir assembly is the liquid reservoir assembly 100 for the refrigerating system according to the above embodiments of the present disclosure. The capillary 4 may be connected to the condenser 7 and the evaporator 8 respectively, the gas input pipe 2 may be connected to the evaporator 8, and the gas output pipe 3 may be connected to the compressor 6.

In the refrigerating system 200 according to some embodiments of the present disclosure, by providing the liquid reservoir assembly 100 for the refrigerating system according to the above embodiments of the present disclosure, the filling quantity deviation of the refrigerating system can be reduced, the phenomenon of the excessive refrigerant or the insufficient refrigerant can be prevent from occurring. Furthermore, the supercooling degree can be increased, the refrigerating capacity per unit volume can be promoted, the refrigerating speed can be enhanced, the refrigerating efficiency can be improved, and the energy consumption can be reduced. Meanwhile, the noise produced by the airflow disturbance can also be reduced, the probability of the liquid strike phenomenon occurring in the compressor 6 can be reduced, and the service life of the compressor 6 can be prolonged.

According to some embodiments of the present disclosure, the gas input pipe 2 may be connected to the evaporator 8 by welding, such that the strength and the reliability of the connection between the liquid reservoir assembly 100 and the evaporator 8 can be enhanced, the manufacturing is facilitated, and the production cost is reduced.

The specific structure and the operation process of the refrigerating system 200 according to some embodiments of the present disclosure will be described in detail below with reference to FIG. 7.

As illustrated in FIG. 7, in the present embodiment, the compressor 6 has an exhaust port 61 and a gas return port 62, the condenser 7 includes a left condenser 71 and a right condenser 72, and an anti-condensation pipe 73 is connected between the left condenser 71 and the right condenser 72 so as to prevent a condensation phenomenon from occurring to the condenser 7. The exhaust port 61 is connected to one end of the left condenser 71, and the other end of the left condenser 71 is connected to one end of the right condenser 72 through the anti-condensation pipe 73. A dry filter 9 is connected between the other end of the right condenser 72 and the liquid reservoir assembly 100, and the dry filter 9 is communicated with the inlet end 41 of the capillary 4.

The inlet end 41 of the capillary 4 is bound to the gas input pipe 2 by the aluminum foil tape 5. The outlet end 42 of the capillary 4 is wound around the outer wall of the liquid reservoir 1. The outlet end 42 of the capillary 4 is connected to an inlet of the evaporator 8, and an outlet of the evaporator 8 is connected to the liquid reservoir 1 through the gas input pipe 2 by welding. The gas output pipe 3 is connected to the compressor 6.

When in operation, the compressor 6 compresses the refrigerant in the compression chamber to work. After being compressed by the compressor 6, the high-temperature and high-pressure refrigerant is discharged out of the exhaust port 61 of the compressor 6, enters the left condenser 71 and the right condenser 72 in turn to perform a heat dissipation, and further enters the capillary 4 via the inlet end 41 of the capillary 4 after being filtered by the dry filter 9, so as to achieve the heat exchange with the refrigerant in the liquid reservoir 1.

After being throttled and depressurized by the capillary 4, the refrigerant enters the evaporator 8 and absorbs heat in the evaporator 8, thus achieving a refrigerating operation. Then, the refrigerant enters the liquid reservoir 1 through the gas input pipe 2, achieves the heat exchange with the refrigerant in the capillary 4 within the liquid reservoir 1, and returns to the compressor 6 through the gas output pipe 3 to be compressed, thereby completing the circulation of the refrigerant in the refrigerating system 200.

Since the capillary 4 is attached to the gas input pipe 2 and wound around the outer wall of the liquid reservoir 1, the refrigerant in the capillary 4 can perform a further heat exchange with the refrigerant in the liquid reservoir 1 during the circulation.

Specifically, the refrigerant liquid after being throttled and depressurized by the capillary 4 can perform the heat exchange with the incompletely evaporated refrigerant in the liquid reservoir 1. On one hand, the refrigerant in the capillary 4 can be further completely liquefied into the refrigerant liquid under the action of the low-temperature refrigerant in the liquid reservoir 1, so as to reach the supercooling effect, such that the supercooling degree can be increased, and the refrigerating capacity per unit volume can be improved. Thus, the refrigerating effect can be promoted, the refrigerating speed can be increased, and the energy consumption can be reduced, so as to improve the purity of the refrigerant liquid entering the evaporator 8, and to reduce the noise produced by the airflow disturbance.

One the other hand, the incompletely evaporated refrigerant in the liquid reservoir 1 can be further evaporated under the action of the high-temperature refrigerant in the capillary 4, the purity of the gaseous refrigerant entering the compressor 6 through the gas output pipe 3 can be improved, and the liquid mixed in the refrigerant returning to the compressor 6 via the gas return port 62 is reduced, such that the liquid strike phenomenon can be prevented from occurring in the compressor 6, the noise hence can be further reduced, and also, the probability of a breakdown of the compressor 6 can be reduced.

In conclusion, since the refrigerating system 200 according to some embodiments of the present disclosure, by is provided with the liquid reservoir assembly 100 according to the above embodiments of the present disclosure, the refrigerating system 200 has advantages of the high refrigerating efficiency, the low energy consumption and the low noise.
